Abstract
The utility model provides a cable pulley exchange device for a crane, which is composed of brackets, a pressure plate, sleeves and nuts, wherein the brackets EW U-shaped screws with threads at two ends; the sleeves are sleeved on two ends of the U-shaped screw inserted into screw holes at two ends of the pressure plate, and the nuts are screwed outside the sleeves. The two U-shaped brackets respectively support two sides of the bottom part of a pulley; an upper pressure plate, the sleeves and the nuts are respectively arranged on the upper part of the bracket extending to the upper surface of an H-shaped beam of the crane, and a rotary nut drives the brackets to ascend until the pulley is lifted in the air, so that the pulley can be exchanged fast. According to the cable pulley exchange device for the crane disclosed by the utility model, the structure is simple, the exchange speed is fast, safety and reliability are achieved without parking, the time and the effort are saved, online fast exchange can be achieved, the exchange time is shortened for more than three times, and the operating rate of the crane is increased greatly.
Description
Technical field
The utility model belongs to flight-line maintenance utensil field, is specifically related to a kind of device that is specifically designed to crane cable coaster fast online replacement.
Background technology
Cable coaster is that the crane cable is carried indispensable important component part.For large-scale crane, because crane master file power of motor is big, therefore the deadweight of the cable that uses is also corresponding bigger, and the dead load that common pulley sheave can bear is carried out matching Design according to the dead load of cable itself mostly.Yet in actual production process, the frequency of utilization of crane is higher, and work rhythm is very fast, and the reciprocating action of coaster is frequent, and pulley almost all was under full load even the overload operation state in 24 hours, thereby caused only have about 15 days the service life of coaster.Under the situation of no specific purpose tool; Time according to the method for routine replacement coaster needs 6-8 people to spend 1 hour could be changed completion; Not only waste time and energy, and need crane to stop fully could to realize, have a strong impact on the operating rate of crane and carrying out smoothly of production.
Summary of the invention
The utility model aims to provide a kind of simple in structure, is convenient to operation, ability fast online replacement cable coaster, thus shortening the replacing time, the crane cable coaster of raising crane production capacity is changing device more.
For this reason, the solution taked of the utility model is:
A kind of crane cable coaster is changing device more, it is characterized in that, is made up of carriage, pressing plate, sleeve pipe and nut; Said carriage is two ends screwed " U " shape screw rods, and the pressing plate two ends are provided with screw hole, and " U " shape screw rod two ends that are inserted in the pressing plate screw hole are with sleeve pipe, is screwed with nut on " U " shape screw rod outside the sleeve pipe.
Method for using of the utility model and effect are:
When changing coaster, earlier two cover " U " shape carriages are held the arse both sides respectively, " U " shape carriage top is extend into more than the crane I-beam upper surface, again pressing plate is installed to respectively on the screw rod of " U " shape carriage two ends; Then " U " shape screw rod two ends are put sleeve pipe respectively, and the nut of outside sleeve pipe, screwing on.Rotate nut respectively and drive both sides " U " shape carriage rising, coaster is carried to unsettled, can change coaster fast until carriage through screw thread.
The utility model is simple in structure, light practicality, and replacing speed is fast, and is time saving and energy saving, safe and reliable and needn't stop, and realized fast online replacement, can shorten the replacing time more than 3 times, greatly improves the operating rate of crane, and what guarantee to produce carries out smoothly.
Description of drawings
Fig. 1 is a more changing device sketch map of crane cable coaster.
Fig. 2 is a more changing device installment state sketch map of crane cable coaster.
Among the figure: carriage 1, pressing plate 2, sleeve pipe 3, nut 4, crane I-beam 5, coaster 6.
The specific embodiment
Visible by accompanying drawing, the utility model crane cable coaster more changing device mainly is made up of two cover carriages 1, pressing plate 2, sleeve pipe 3 and 4 on nut.Carriage 1 adopts the shape screw rod system of simmering in two ends screwed " U " to form, and " U " shape screw rod two distance between tie rods are slightly larger than the baseplate width of crane I-beam 5.Strip pressing plate 2 two ends respectively are processed with a screw hole, and the distance in two screw rods hole is identical with two " U " shape screw rod spacings.Sleeve pipe 3 is to adopt the galvanized pipe intercepting to process.For avoiding lost, also can the utility model be fitted together when not using, be about to pressing plate 2 and be sleeved on " U " shape screw rod of carriage 1, put the nut 4 of screwing in " U " shape screw rod end again behind the sleeve pipe 3.
Change before the coaster 5; Earlier the utility model is disassembled, again carriage 1 is held the two bottom sides of coaster 6, and carriage 1 upper end that will reach above the crane I-beam 5 is installed pressing plate 2 and sleeve pipe 3 respectively; The nut 4 of outside sleeve pipe 3, screwing on again rotates the replacing operation that nut 4 can carry out coaster 6 then.
